Abstract

The invention discloses a method for producing a coal cutter cable prevented from not being pierced, and relates to the technical field of coal cutter cable production. According to the method, three power line cores and a control line core are squeezed and wrapped together. The method specifically comprises the first step of manufacturing the power line cores and the control line core, the second step of squeezing and wrapping the power line cores and the control line core through a sheath, the third step of winding the sheath with a steel wire braiding net, and the fourth step of wrapping the steel wire braiding net with an adhesive tape sheath. The method has the advantages that the cable produced through the method is anti-tearing, pulling resistant and smashing resistant when damaged by machines, and sharpen articles are prevented from piercing a sheath layer of the cable.

Description

A kind of anti-electric cable for coal mining machine production method of thrusting

Technical field

The present invention relates to electric cable for coal mining machine production technical field, specifically a kind of anti-electric cable for coal mining machine production method of thrusting.

Background technology

Known cable comprise power core, core, control core and sheath.This structural cable can only be used in general environment, and for the severe place of environment, cable cover(ing) can not prevent mechanical damage effectively, as: sharp object, the factor such as pound, squeeze, drag.

Summary of the invention

In order to overcome known cable cover(ing), can not effectively prevent the shortcoming of mechanical damage, the invention provides a kind of anti-electric cable for coal mining machine production method of thrusting; The cable that production method is produced, when being mechanically damaged, can effectively prevent that sharp object from thrusting, and cable has tear-proof, resistance to pulling force, resistance to punching and pounds.

The present invention realizes with following technical scheme: a kind of anti-electric cable for coal mining machine production method of thrusting, and together with 3 power cores are extruded in a control core, concrete making step is as follows:

1. make power core and control line step;

2. in power core and control core periphery, extrude the step of sheath;

3. in sheath periphery, be wound around the step around braided steel wire net;

4. the step of rubberized tape sheath outside braided steel wire net periphery parcel.

It is further: described power core has power line core conductor, and making step is: first on power line core conductor, be enclosed with power line core insulation layer, then on power line core insulation layer, be enclosed with rubberized tape.

Described control core has 4 control line core conductors, and making step is: be to be first enclosed with control line core insulation layer in control line core conductor 1 periphery, then 4 control line core conductors 1 that are enclosed with control line core insulation layer be extruded in together.

Described braided steel wire net is woven into cylinder by finer wire and makes in flattening.

Advantage of the present invention: the cable that the method is produced, when being mechanically damaged, having tear-proof, resistance to pulling force, resistance to punching and pounds, and has stoped sharp object to thrust the coat layer of power cable.

Accompanying drawing explanation

Fig. 2 is the schematic top plan view of Fig. 1.

In figure: 1. control line core conductor, 2. power line core conductor, 3. power line core insulation layer, 4. rubberized tape, 5. sheath, 6. braided steel wire net, 7. outer rubberized tape sheath.

Embodiment

An electric cable for coal mining machine production method of thrusting, together with 3 power cores are extruded in a control core, concrete making step is as follows:

1. make power core and control line step;

2. in power core and control core periphery, extrude the step of sheath;

3. in sheath periphery, be wound around the step around braided steel wire net 6;

4. the step of rubberized tape sheath 7 outside braided steel wire net periphery parcel.

As depicted in figs. 1 and 2, power core has a power line core conductor 2, on power line core conductor 2, is enclosed with power line core insulation 3 cable of producing through the method, on power line core insulation layer 3, is enclosed with rubberized tape.Power line core insulation layer 3 and rubberized tape 4 are integrated through vulcanization crosslinking.Control core and there are 4 control line core conductors 1, in control line core conductor 1 periphery, be enclosed with control line core insulation layer, then 4 control line core conductors 1 that are enclosed with control line core insulation layer are extruded in together.In the middle of 3 power cores and a control core, be provided with ground core.

Ground core, control core, power core, sheath 5 and the wrapped braided steel wire net 6 in sheath periphery and the wrapped rubberized tape sheath 7 in braided steel wire net 6 peripheries are by sulfuration, and sheath, braided steel wire net and three of rubberized tape sheaths are cross-linked into one.Described rubberized tape is the sizing material of same nature, through rubber operation, is made; Described braided steel wire net is woven into cylinder by finer wire and makes in flattening.

In the present embodiment, control line core conductor 1 is kinked around structure and is formed by tin-coated copper tow.Power line insulating barrier 3 extrudes and forms by having excellent electrical, low temperature resistant, resistance to ozone, ethylene-propylene diene copolymer heat-resisting, ageing-resistant performance, has excellent electric property and good physical and mechanical properties.Rubberized tape 4 is made into band shape by ethylene-propylene diene copolymer through rubber technique.Sheath 5 is to have haloflex material fire-retardant, warping strength, heat-resisting, chemical resistance corrosion to extrude and form, and has good physical and mechanical properties, can effectively prevent mechanical damage.Improved the useful life of cable electrical property and prolongation cable.Braided steel wire net 6 for high strength thin steel wire is woven into cylindric flattening make.Outer rubberized tape sheath 7 is fire-retardant by having, warping strength, heat-resisting, the haloflex material of chemical resistance corrosion is made into band shape through rubber technique.The cable that the method is produced has guaranteed that cable is when being mechanically damaged, and can effectively prevent that sharp object from thrusting, and has tear-proof, resistance to pulling force, resistance to punching and pounds, and has also guaranteed the flexibility of whole cable.
